Overview

TESTCOIN

Python implementation of a blockchain.

Description

The Testcoin implementation is focused almost exclusively in the hashed ledger feature. It does include some advanced feature like a distributed nodes and a consensus protocol via proof of work. which is just a simple function not a complex algorithm.

The goal of this project is to explain and to make clearer how is a blockchain structured at the very core. It's not built with the intention to replicate an advanced blockchain like Bitcoin or Ethereum.
